Plug-in hybrid , simply Plug-in or rechargeable hybrid on plug. These are some of the definitions with which PHEV vehicles (Plug-in Hybrid Electric Vehicle) are identified, that is; cars that have an internal combustion engine combined with one or more; unit & agrave; electric powered by a battery of a certain capacity; that can & ograve; be recharged from an external socket. Accumulator that allows the vehicle to travel a few tens of km with the petrol engine off (on average around 50-60 km).
We therefore decided to take the model Opel Grandland Hybrid4 to better understand how this technology works inside the German SUV.
THE PLUG-IN TECHNOLOGY 
Many identify the Plug-in system as the perfect “bridge” between endothermic and electric. No autonomy anxiety like in the electric & quot; pure & quot; given the presence of the internal combustion engine. Thanks to the electric motor and the battery of a certain capacity; (usually around 10-15 kWh) people can get used to driving in electric only for several km and above all to manage autonomy and recharge .
The general operating scheme is; very simple. Thermal and electric motor can work together as in Full Hybrids. However, thanks to the Plug-in battery, the electric thruster can provide traction to the car for a few tens of km, leaving the internal combustion engine off. Usually, drivers have different operating logics of the hybrid system at their disposal that they can choose to give priority; electric traction, performance or battery charge conservation.
Obviously & egrave; regenerative braking is always presentwhich, in some models, can & ograve; be managed thanks to availability; of different levels of energy recovery. Hybrid technology also allows you to bring more & ugrave; easily four-wheel drive on cars. For example, it will suffice; a unit electric for each axis without having to resort to more solutions; complex, bulky and heavy. In some cases, Plug-in technology can be a solution to make a greater level of power available without having to focus on more endothermic engines; powerful but with significantly higher consumption.
Using the Plug-in technology correctly (always recharging), especially in some areas, such as driving in the city, & egrave; possible to significantly reduce consumption.
QUESTIONS AND ANSWERS 
What's the difference? between a & # 39; hybrid and a & # 39; Plug-in hybrid?
Sometimes there is a little of confusion when talking about the Plug-in as in some contexts the term & quot; hybrid & quot; is used generically. This can lead people to think that hybrid technology is still the same. Obviously, it is not; real. The hybrid, whether it is Mild Hybrid or Full Hybrid, is always characterized by the internal combustion engine that recharges the battery (also through regenerative braking). In the Plug-in models, on the other hand, the accumulator can always be recharged even through a power outlet or a public column.
Another clarification should be made. It is often thought that Plug-in technology is only available to cars equipped with a petrol engine. Instead, there are, although not many, PHEV models equipped with a diesel engine. Think, for example, of the Mercedes GLE 350 de 4MATIC Plug-in hybrid.
What happens if I don't recharge a Plug-in hybrid car?
As mentioned above, a Plug-in car must be used correctly in order to get the best efficiency possible. In fact, by not filling the battery with energy, the internal combustion engine will enter during the journey; more in function with the obvious consequence that consumption will increase.
To make the most of these cars, & egrave; It is important to have a power socket in the box at home. In this way it will be; It is possible to fill up with energy in the evening to find the car ready and charged up the next morning.
How much do plug-in hybrid cars pay?
This technology offers a number of advantages, including fiscal ones. In fact, hybrid cars (not just Plug-ins), depending on the Region, do not pay the stamp duty in the first years up to 5.
What are the disadvantages of a Plug-in hybrid car?
The main one is; the cost. These models, in fact, have a high price. In addition, their technology more & ugrave; complex can & ograve; lead to more coupons expensive. The Plug-ins, due to the presence of the electric motor and the battery, weigh a lot and this can; reduce their efficiency if the recharge and therefore the electric motor are not used.
Are there discounts for Plug-in hybrid cars?
< blockquote>
The Government has provided incentives for the purchase of these cars equal to 2,000 euros without scrapping or 4,000 euros with scrapping. The new car, however, cannot cost more; of 45 thousand euros + VAT. In addition, hybrid cars can have access in restricted traffic areas where endothermic models cannot circulate.
